Hi

Well now that you are committed to the project, it's time for the wish list:

1) Make the beast easier to calibrate and keep in calibration. 
2) Improve the accuracy.
100) Add cool features like Avar.

The 5370 dates to a period when the idea of software based calibration was a
bit "out of the box". Weather anything can be done purely in code or not -
no idea. You don't have all the hooks and fiddlers that a more modern box
would have. Anything that helped out on items 1 and 2 would make a swap out
worth it. 

Bob

Well the hard part (or maybe the fun part) is still to come.
I wasn't going to talk about any of this until I had a board to sell, but
this thread sort of forced the issue, lol.
